Abstract

PURPOSE:To display different and related ranges included in a source program on the same screen by displaying different ranges in the source program on the left-hand half and the right-hand half as a screen display system. CONSTITUTION:A screen display means 3 specifies and the sets the to row numbers of two ranges in the source program that a display range setting part 31 displays to pointers 7 and 8, whereby display start positions are set to two row numbers of the source program lying on a work file 2. A screen display means 32 displays the step concerned in the source program by one line in the left-hand half on the screen by the pointer 7. After one-line display ends, the contents of the pointer 7 are counted up by one, and source steps are sequentially displayed on the screen until they fill the left-hand half of the screen. According to the similar procedure the screen display means 32 displays the 2nd display range with the row number shown by the pointer 8 as a display start position in the right-hand half of the screen.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a split display method for a text editor in which the screen display of a program for editing a source program in a text editor is divided into left and right halves.

[Conventional technology]

In conventional technology, when displaying the contents of a source program on a screen in a text editor, one range on the program is targeted, and one line on the source program is displayed for each line on the display screen, as shown in Figure 3. was displayed.

[Problem that the invention seeks to solve]

In the screen display method of such a conventional text editor, only one range on the source program was displayed, so there was a drawback that other related ranges could not be viewed on the screen at the same time.

SUMMARY OF THE INVENTION An object of the present invention is to provide a split display system for a text editor that solves these drawbacks and allows related programs to be displayed on the same screen.

[Means for solving problems]

The present invention provides a split display method for a text editor in which a source program is edited using a keyboard and a CRT display means. The present invention is characterized by having a screen display means for displaying a range designated by two pointers indicating independent display start positions in a source program being displayed on the same screen by dividing it into left and right halves.

〔Example〕

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a process diagram illustrating one embodiment of the present invention. In this embodiment, source file 1 stores a source program to be edited in a text editor.
, a work file 2 that temporarily stores the edited and corrected source program 20, and a pointer that points to the first line of each of the left and right display areas on the split screen and stores the corresponding line number in the source file. 6 and a pointer 7, a work file storage means 3 for storing the contents of the source file 1 in the work file 2, and a screen display means 4 for displaying the source program stored in the work file 2 split on the left and right sides of the screen. It is comprised of a processing section 10 for displaying a split screen, a CR7 display device 5 and a keyboard 6, which are devices for inputting commands for displaying a split screen, editing of source programs, and the like.

Next, the flow of the work file storage means 2 is that the source program 10 is first read from the source file 1, the source program is read by the reading section 21, and then the work file 2 is read.
This work file 2 is stored in the work file output section 2.
Read from 2. The flow of the screen display means 4 is as follows: First, the display range setting section 31 sets the display range for the output from the work file 2, the screen display section 32 creates the output for screen display, and the output is displayed on the CRT display section 5. do.

Next, the operation of this embodiment will be explained in detail.

In the work file storage means 2, the source program reading section 21 reads in each reading unit from the source file 1 in which the source program 10 to be edited is stored, and the edited source program is read by the work file output section 22. are sequentially output to work file 2, which is a temporary storage location.

Next, in the screen display means 3, the display range setting section 31
By specifying/setting the first line numbers of the two ranges that you want to display on the source program to pointer 7 and pointer 8, the display start position is set to the two corresponding line numbers in the source program that exists in work file 2. be done.

First, of the two pointers whose display start positions are set by the screen display means 32, pointer 7 is used to move the corresponding step in the source program to the left half of the screen.
Display the line, and when this one line display is finished, increase the contents of pointer 7 by 1 until the entire left screen is displayed.
The source steps are sequentially displayed on the screen. When the screen display with the line number indicated by pointer 7 as the display start position is completed, the next step is to use the screen display means 32 in the same procedure as pointer 7 to set the line number indicated by pointer 8 as the display start position. The second display range is displayed in the right half area on the screen. When the entire right half of the screen is displayed, a split screen as shown in FIG. 2 will be displayed.

〔Effect of the invention〕

As explained above, according to the present invention, as a screen display method in a text editor, a certain range of the source program is displayed on the left half of the screen, and another range is displayed on the right half of the screen, so that they can be related to each other. It becomes possible to display different ranges in a source program on the same screen, and related program work can be performed efficiently.
